Ingredients for sweet potato strips
Eight ingredients transform humble sweet potatoes into addictively crispy, restaurant-quality strips.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 large | Organic preferred, peeled |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | High quality, fruity |
| Smoked Paprika 🌶️ | 1 tsp | For smoky depth |
| Garlic Powder 🧄 | ½ tsp | Freshly ground preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Diamond Crystal Kosher Salt 🧂 | 1 tsp | Fine grain preferred |
| Fresh Rosemary 🌿 | 1 tbsp | Chopped finely, stems removed |
| Fresh Thyme Leaves 🌿 | 1 tbsp | Or dried thyme at 1/3 amount |
| Cornstarch 🌾 | 1 tbsp | For extra crispiness |
| Lemon Juice 🍋 | 1 tsp | Freshly squeezed |
The sweet potatoes are non-negotiable here—organic, firm varieties like Jewel or Beauregard work best. Trader Joe's and Whole Foods carry excellent options, or grab the standard orange ones from any grocery store. Skip the green-tinted ones (they're underripe). For the olive oil, California avocado oil or Spanish extra-virgin adds subtle flavor, but any high-quality oil works. The cornstarch is what creates that shatteringly crisp texture—don't skip it. I always buy mine in bulk from Amazon for better pricing, but the tiny boxes at Walmart work fine too.
No smoked paprika? Regular paprika plus a pinch of cayenne gets you close. Fresh rosemary and thyme are ideal, but dried works at one-third the amount. The lemon juice can be swapped for white vinegar if you're out, though it'll have a slightly different tang. For extra crunch, toss the strips in a second coat of cornstarch after the first air-fry. Want more heat? Add ½ tsp cayenne pepper to the seasoning mix. The strips reheat beautifully—just pop them back in the air fryer for 2-3 minutes.
Store any leftovers in an airtight container for up to 3 days—they lose crispiness over time, so reheat before serving. For longer storage, freeze the strips on a parchment-lined tray for 1 hour, then transfer to a bag for up to 3 months. To reheat from frozen, air-fry at 375°F for 5 minutes. These strips make perfect snacks, topping for salads, or base for loaded fries. Double the batch—they disappear fast!

Step-by-step instructions for air-crisped sweet potato strips
Here's how to transform humble sweet potatoes into irresistibly crispy, golden strips with a perfect balance of smoky and herby flavors.
Prep and Cut the Sweet Potatoes
Start by peeling the 2 large sweet potatoes using a vegetable peeler or sharp knife. I like to use organic sweet potatoes when possible—their thinner skins make peeling easier and the flesh stays vibrant. Cut each potato lengthwise into 3 equal wedges, then slice each wedge into ¼-inch thick strips. You should end up with about 4 cups of uniform strips.
For even cooking, I recommend cutting the strips on a cutting board using a sharp chef's knife. Hold the knife at a slight angle and use a gentle rocking motion to create clean, even slices. If you're worried about uneven strips, you can run them through a mandoline for perfect consistency—but a sharp knife works just fine with practice.
Season and Toss with Cornstarch
In a large bowl, combine the sweet potato strips with the 1 tablespoon cornstarch. This is your secret weapon for achieving that perfect crispy exterior. Toss the strips until they're evenly coated with the cornstarch, shaking off any excess. Next, add the 2 tablespoons extra-virgin olive oil, 1 teaspoon smoked paprika, ½ teaspoon garlic powder, ½ teaspoon ground black pepper, and 1 teaspoon diamond crystal kosher salt.
Grab two forks and really work the seasoning into every strip. You want each piece to be thoroughly coated in the oil and spices. I like to press the forks together and twist them to ensure the seasoning penetrates the edges. This step is crucial—it guarantees even flavor and that delicious crunch we're after.
Add Fresh Herbs and Lemon Juice
Add the 1 tablespoon finely chopped fresh rosemary and 1 tablespoon fresh thyme leaves to the bowl. The bright, aromatic herbs will complement the smoky paprika beautifully. Finally, drizzle in the 1 teaspoon freshly squeezed lemon juice and toss everything together one last time. The acidity from the lemon juice helps balance the sweetness of the potatoes and adds a subtle brightness to the finished strips.
Here's a pro tip: If you're using dried thyme, reduce the amount to ⅓ of what's called for in fresh herbs. The flavor will be concentrated, so less goes a long way. Give everything one final toss to distribute the herbs and lemon juice evenly throughout the mixture.
Arrange for Perfect Air-Crisping
Preheat your air fryer to 400°F. While it's heating, transfer the seasoned sweet potato strips to the air fryer basket in a single layer, making sure they don't overlap. If you're short on space, you can work in batches—just don't overcrowd the basket. The strips need room to breathe and circulate air for that perfect crisp.
For even cooking, I recommend arranging the strips in a single layer with the cut sides facing up. This allows the hot air to hit all surfaces evenly. If your air fryer has a rack, use it to elevate the strips slightly—this helps with airflow and prevents soggy bottoms.
Air-Crisp to Golden Perfection
Place the basket in the preheated air fryer and cook for 12-15 minutes, shaking the basket every 5 minutes to ensure even browning. You're looking for strips that are deep golden brown with crispy edges. The exact time may vary slightly depending on your air fryer model, so keep an eye on them.
Here's how to know they're done: The strips should be crispy to the touch and have a deep golden color. If they're browning too quickly, you can reduce the temperature to 375°F for the last 2-3 minutes. Once they're perfectly crisp, transfer them to a serving platter immediately. The strips will continue to crisp slightly as they cool, so don't worry if they're not rock-hard when you take them out.
Pro Tips For Making Sweet Potato Strips
- CUT THIN, CUT EVEN: Sweet potatoes are stubborn—uneven strips mean some burn while others stay raw. Use a mandoline (or a sharp knife with a ruler) to slice them ¼-inch thick, then rotate the potato 90 degrees and slice again for consistent pieces. Trust me, your patience here pays off in crispy perfection.
- SALT THE POTATOES FIRST: Skip this and your strips will turn soggy. Toss the raw sweet potato slices with ½ teaspoon salt per pound and let them sit for 10 minutes before cooking. The salt draws out moisture, which means better browning and less oil splatter—your pan will thank you.
- DON’T OVERCROWDLE THE PAN: I learned this the hard way—packing the pan too tight steams the potatoes instead of crisping them. Work in single-layer batches over medium-high heat, giving them space to sizzle. If you’re impatient like me, use a larger skillet or cook in two rounds. Crispy strips aren’t made in a crowd.
- UPGRADE WITH ACID: Sounds weird, but it works: Toss the cooked strips with ½ teaspoon lemon juice or vinegar while they’re still hot. It brightens the smoky flavors and cuts through the richness of the olive oil. My grandmother swore by this, and she was right—it’s the thing that makes these strips taste restaurant-worthy.
Troubleshooting this dish
Uneven Cooking
If your sweet potato strips emerge soft in the center or burnt on the edges, it’s likely due to uneven airflow. First, ensure you’re not overcrowding the air fryer basket—strip them in a single layer with space between each piece.
I’ve found that Ninja Foodi air fryers handle batches better than some competitors, but even they struggle if overloaded. For thicker strips (¼ inch), reduce the temperature to 375°F and increase cooking time by 2-3 minutes. Shake the basket every 5 minutes to redistribute heat. 🌡️
Soggy Strips
Soggy sweet potato strips usually mean excess moisture or insufficient cornstarch. Double-check that you’ve tossed the strips thoroughly with the 1 tablespoon cornstarch—this is non-negotiable for crispiness. If you’re using freshly peeled sweet potatoes, pat them very dry with a kitchen towel before cutting.
For extra insurance, let the strips sit in the bowl for 5-10 minutes after seasoning to absorb any residual moisture. Pro tip: If you’re short on cornstarch, swap in 1 tablespoon arrowroot powder—it works just as well. 💡
Strips Stick Together
Sticky strips are often caused by too much oil or insufficient tossing. Measure your 2 tablespoons olive oil precisely—don’t eyeball it. After tossing, spread the strips on a parchment-lined tray for 5 minutes to let excess oil drip off.
For stubborn batches, lightly coat the air fryer basket with nonstick spray before adding the strips. If they’re still clumping, reduce the oil to 1 tablespoon and add ½ teaspoon extra cornstarch to the seasoning mix. 🍠
Burnt Edges
Burnt edges happen when the air fryer runs too hot or the strips are too close to the heating element. First, verify your air fryer is preheated to 400°F—some models underreport temperatures.
If your strips brown too quickly, reduce the temperature to 375°F for the final 3-5 minutes of cooking. For stubborn models, try flipping the basket upside down halfway through cooking to adjust heat distribution.
I’ve also had success using a silicon mat in the basket to create a barrier between the strips and the heating element. 🔥
Sweet Potatoes Too Soft
Overly soft strips usually mean undercooking or using underripe sweet potatoes. Always select firm, vibrant sweet potatoes—avoid any with soft spots or green-tinted skin. For extra structure, soak the peeled strips in ice water for 10 minutes before seasoning (this firming-up trick works wonders).
If they’re still too soft after cooking, increase the temperature to 410°F and cook for an additional 2 minutes. For a firmer bite, reduce the cornstarch to ½ tablespoon and add ½ teaspoon baking powder to the seasoning mix—it adds a subtle lift. 💪

Frequently asked questions
Can I make these sweet potato strips without an air fryer?
For an oven version, spread strips on a parchment-lined baking sheet and bake at 425°F for 18-22 minutes, flipping halfway. For a stovetop method, heat ¼ inch of oil in a skillet over medium-high heat and fry strips in batches for 3-4 minutes per side until golden. The oven method yields slightly crispier results than frying.
How do I store leftover sweet potato strips?
Store in an airtight container for up to 3 days at room temperature, but they'll lose some crispiness. For longer storage, freeze on a parchment-lined tray for 1 hour, then transfer to a bag for up to 3 months. To reheat frozen strips, air-fry at 375°F for 5 minutes or bake at 400°F for 8-10 minutes. Microwaving works but makes them soggy.
What's the best way to cut sweet potatoes into even strips?
Use a sharp chef's knife and cut each potato lengthwise into 3 equal wedges first. Hold the wedge flat and slice into ¼-inch strips using a gentle rocking motion. For perfectly uniform strips, a mandoline with a ¼-inch blade works best. Always cut against the grain of the potato fibers for cleaner slices.
Can I use regular potatoes instead of sweet potatoes?
While you can substitute regular potatoes, they won't have the same sweet, caramelized flavor. If you must use them, choose waxy varieties like Yukon Gold and reduce cooking time by 2-3 minutes. The strips will be less sweet and more starchy. For best results, stick with sweet potatoes—they're designed for this recipe!
What are the best toppings or dips for these strips?
Try these crowd-pleasers: spicy mayo (mayo + sriracha), garlic aioli, cooling Greek yogurt dip (yogurt + lemon + dill), or smoky chipotle crema. For toppings, sprinkle with crumbled feta, pickled jalapeños, or toasted sesame seeds. The strips pair perfectly with tacos, salads, or even as a crunchy pizza topping!
